Thermal Activation of Asymetrical Composites for Vibration Control

Abstract

<p align="justify"> <span><span style="font-family:Verdana;">The CBCM </span><span style="font-family:Verdana;">(Controlled Behaviour Composite Material) is a thermal active composite, which </span><span style="font-family:Verdana;">has been developed for morphing applications. The thermal activation is made by </span><span style="font-family:Verdana;">a source of heating generated within the composite structure. The coupling </span><span style="font-family:Verdana;">between the induced thermal field and the thermomechanical properties of the </span><span style="font-family:Verdana;">various components of the composite structure leads to the change of the </span><span style="font-family:Verdana;">structure shape. The heat source is generated by Joule effect, Carbon yarns </span><span style="font-family:Verdana;">inserted in the composite, are connected to a power supply. The application </span><span style="font-family:Verdana;">field of CBCM technology is the domain of shape modification and active </span><span style="font-family:Verdana;">assembly. The objective of this work is to illustrate the capabilities of CBCM </span><span style="font-family:Verdana;">in the domain of vibration control. We will study several reference plates with </span><span style="font-family:Verdana;">different constitution. The influences of these different constitutions, of the </span><span style="font-family:Verdana;">CBCM effect and the loss of stiffness for the matrix will be highlighted, for </span><span style="font-family:Verdana;">two boundary conditions, free/free and embedded/embedded.</span></span> </p
